Worksheet on Magnetic Energy

Worksheet on magnetic energy contains various types of questions.

The important information will help us to the answer the questions given below.

Electromagnet: A temporary magnet, developed within a magnetic substance by electrical energy.

Magnet: A piece of iron having a special power to attract other iron bodies towards it.

Demagnetization: Removal of the magnetic properties of a magnet.

Magnetization: Method of developing magnetic properties in a magnetic substance.

Magnetic substance: The substances, which are attracted by a magnet and can be magnetized by magnetic induction.

Magnetic pole: The two opposite ends of a magnet, which have the strongest power of attraction.

I. Write true or false of the following:

(i) Very high temperature makes a magnet weak.

(ii) Magnetic energy flows through a copper wire.

(iii) A magnet, wrapped with a plastic sheet cannot attract a piece of iron any more.

 (iv) South pole of a magnet always attracts the south pole of another magnet.

 (v) When a piece of iron is kept near a very strong magnet it becomes hot.

 

II. Fill in the blanks: 

(i) The property of ________ helps us to distinguish between a pair of magnets and a pair of iron bars.

(ii) South pole of a bar magnet repel the ________ pole of another magnet.

(iii) An iron bar placed near a magnet behaves like a ________.

(iv) North pole of a magnet attracts ________ pole of another magnet.

(v) The door of a refrigerator get tightly closed by ________.

 

III. Answer the following questions:

(i) If a pin head is held near the mid-point of a magnet bar, what will happen?

(ii) If a piece of wood is kept near a magnet bar, what will happen?

(iii) How can you separate iron filings from sand?

(iv) What will happen if the North pole of a magnet is held near the South pole of another magnet?

(v) Ron have two magnets and a iron bar. How can you identify the iron bar out of it?

(vi) What happens when a piece of iron is held near a bar magnet?

(vii) How can we transform an iron bar into a magnet bar?

(viii) How can we transform a magnet bar into an ordinary iron bar?

(ix) Suppose if we keep a magnet in fire for sometime what will happen?

(x) What will happen to an electromagnet if you disconnect the power supply?
